Question

· The three angles of a triangle are in the ratio 2:3:4. Find the measure of the greatest angle.​

Answer 1

Step-by-step explanation:

lets the angle be X

2x+3x+4x=180°(angle sum property)

9x=180

x=20

therefore greatest angle will be 4x which will be

4x=80°

Answer 2

Answer:

2x+3x+4x=180

9x=180

x=180÷9

x=20

2x=2×20=40

3x=3×20=60

4x=4×20=80

the greatest angle is 80
